Update: Ford no longer does stud install...
I've called numerous dealers with recommendation from people on here that they do head studs.... Spoke with the proper people that were recommended to me to talk to. and ALL have told me they recently no longer do head stud installation as ford will now not allow it. I then proceeded to call every Dealer in San Diego to Los Angeles and they all said no. Lists includes: Kearny Mesa, Mossy, Drew, Fuller, El Cajon, Perry, Encinitas, Homor Heller, Ken Grody, North County, Santa Margarita, Tuttle Click, Sunrise in Fontana, Fritts, and Raceway... THEY ALL SAID NO!
Here is the reason why: Ford has a procedure for the head gaskets which don't involve pulling the cab off or removing the engine. Both save time and money. In order to do head studs I was told the labor is more extensive. Ford dealers are now no longer doing it because when a truck comes to the shop wanting head gaskets replaced and they already have head studs, ford will not pay for the extra labor and cost to have them done again. Ford has RECENTLY made a strict policy saying they won't warranty work with head studs.
What I was told the only way I could have head studs installed would be if I personally knew a tech who would not comply with ford's rules and would be willing to do the labor either for a friend or with a paid compensation. With that being they could lose their job on their own accord. From the techs I spoke to, they all sounded unwilling to lose their job with compensation $$.
I received PM's regarding certain dealers from members in this forum and spoke with the people who they knew, and they told me sorry they no longer do them.
So if anyone in Southern California who now wants head studs to be installed through warranty, I hope you have a buddy diesel tech who will do it for you. For those who have told me otherwise and state on here they Ford does warranty head stud installation, give them a call and ask. I'm guessing california dealers and techs are more unwilling to go against fords policies. Sounds to me the small town dealers are more opt to performing this procedure to its customers.
